Androidは画像とパラメータ(属性)をサーバにアップロードします

まず環境について説明します.
サーバはjava eeのservletです
クライアントはandroid
クライアントのコアコード:apache-mime 4 j-0.6とhttpmime-4.0の2つのパッケージをインポートする必要があります.の

  //         
        HttpPost httpPost = new HttpPost(urlsString);
     //       
            MultipartEntity reqEntity = new MultipartEntity();
            if (!file1.getAbsoluteFile().equals(""))
            {
                FileBody fileBody = new FileBody(file1);
                reqEntity.addPart("pic", fileBody);
            }
            StringBody type = new StringBody("wish");
            reqEntity.addPart("type", type);
            if( type.equals("wish") )
            {
                StringBody temp = new StringBody(iWishID + "");
                reqEntity.addPart("temp", temp);
            }
            else
            {
                StringBody temp = new StringBody(sUserName);
                reqEntity.addPart("temp", temp);
            }
            httpPost.setEntity(reqEntity);
            //      HttpClient
            HttpClient httpclient = new DefaultHttpClient();
            //   HttpResponse
            HttpResponse httpResponse = httpclient.execute(httpPost);
            // HttpStatus.SC_OK      
            if (httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK)
            {
                //         
                String strResult = EntityUtils.toString(httpResponse.getEntity());
                System.out.println("yes!");
            }
            else
            {
                System.out.println("no!");
            }

サーバの受信コード(POST):commons-ioが必要である.JArとcommons-io.JArサードパーティ製パッケージ

 protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {  
        boolean isMultipart = ServletFileUpload.isMultipartContent(request);  
        if (isMultipart) {  
            FileItemFactory factory = new DiskFileItemFactory();  
            ServletFileUpload upload = new ServletFileUpload(factory);  
            try {  
                List items = upload.parseRequest(request);  
                Iterator iter = items.iterator();  
                while (iter.hasNext()) {  
                    FileItem item = (FileItem) iter.next();  
                    if (item.isFormField()) {  
                        //          
                        String paramName = item.getFieldName();  
                        String paramValue = item.getString();  
                        System.out.println(paramName + ":" + paramValue);  
                    } else {  
                        //          
                        String fileName = item.getName();  
                        byte[] data = item.get();  
                        String filePath = getServletContext().getRealPath("/files") + "/" + fileName;  
                        FileOutputStream fos = new FileOutputStream(filePath);  
                        fos.write(data);  
                        fos.close();  
                    }  
                }  
            } catch (FileUploadException e) {  
                e.printStackTrace();  
            }  
        }  
        response.getWriter().write("UPLOAD_SUCCESS");  
    }
